The velocity (\(V\)) of the airflow in the context of a GE YF120 or any gas turbine engine in aircraft design can be calculated using the formula:
- V is the velocity of the airflow (in meters per second, m/s).
- m is the mass flow rate (in kilograms per second, kg/s).
- rho is the air density (in kilograms per cubic meter, kg/m³).
- A is the cross-sectional area through which air enters the engine (in square meters, m²).
